Environmental sensing

Abstract

One apparatus embodiment includes an electronics assembly including an environmental sensor, memory that provides data storage, a logic circuit, an indicator component, and a power source for providing power to at least one of the logic circuit and the memory. The logic circuit can be designed to perform a time measurement, perform an environmental measurement with the environmental sensor, and/or initiate an alarm status when a calculated alarm event time occurs based upon the environmental measurement. The indicator component can be connected to the logic circuit for displaying the alarm status.
